2. Description of the Related Art For example, in a digital broadcast receiving system using a satellite, a video / audio signal is compressed using a digital signal compression technique and a stream (trans) in which video / audio digital signals of a plurality of programs are time-division multiplexed. The port stream) is broadcast via a transponder (satellite repeater). On the other hand, a broadcast receiving apparatus for receiving such a digital broadcast selects one of a plurality of transponders of a digital broadcast received through an antenna with a tuner, and selects one of a plurality of channels included in this one transponder. Is selected by demultiplexing, and the digital signal of the selected channel is decoded to output a video / audio signal.

By the way, conventionally, a video cassette recorder (VCR) has been used to automatically set a reserved channel and record the received program at the time when the reserved program starts. In recent years, the broadcast receiving device for receiving the digital broadcast described above includes a remote controller for controlling the video cassette recorder, and when the reserved program starts, the remote controller operates the video cassette recorder. Some video recorders are automatically operated and the received digital broadcast program is recorded on the video cassette recorder.

[0004]

However, as described above, it is considered that the number of programs broadcast by digital broadcasting is enormous, and the chances of program reservation and recording are increased. With this technology, it is expected that the time and effort of the user will increase due to the increased number of recording opportunities. For example, if you have reserved three programs for recording,
When two are common genres and one is another genre,
When recording a program of a common genre on a specific cassette tape, the user needs to replace the cassette tape. Further, in recent years, there has been proposed a device which implements IEEE 1394 as an interface and records a received program on an external recording device such as a D-VHS. However, when connecting a plurality of such external recording devices, the receiving device side holds a list of connected devices indicating what recording devices are connected, and selects recording target devices one by one at the time of recording reservation. Such operations are required.

In view of the above circumstances, it is an object of the present invention to provide a broadcast receiving device with a recording device control function, which can automatically record a received program using an arbitrary recording device.

[0006]

A storage means for storing the recording history of the genre of the program is provided, and when the program guide based on the program information extracted from the digital broadcast wave is output, the program of the genre with a large number of recording executions is preferentially selected and presented. You may do it. According to this, when the program guide is output in a form such as a “recording reservation dedicated program guide” different from the normal electronic program guide, the number of recording executions is large, for example, from the electronic program guide data for one week. The program of the genre is preferentially selected and presented, and the user can efficiently make a recording reservation by viewing the presented content.

Further, the broadcast receiving apparatus with the recording apparatus control function of the present invention designates the program reservation means for accepting the recording reservation of the program, the program series and the recording apparatus in charge of recording the program of the series. Recording device selection means for accepting, an interface for transmitting and receiving data and control information to and from the recording device, and control for recording a series program received by reservation execution on the recording device in charge of the recording using the interface. Means and are provided.

With the above configuration, for example, when the first recording device and the second recording device are connected, the first recording device is designated to record a certain series drama. That is, the first recording device is automatically selected and recorded when the series drama is received and recorded.

In the above structure, the tape position information after the recording of the series program is acquired from the recording device by the interface and stored, and the tape position stored at the time of recording the next series program is stored. A tape drive command is given to the recording device by the interface so that tape position information matching the information is obtained,
It is preferable that the series program be recorded from the coincident tape position. According to this, a series of series programs can be continuously recorded on one recording tape.

The MPU 17 controls the broadcast receiving apparatus 30 as a whole, and particularly executes the following program recording control as the control according to the present invention.

FIG. 2 is a flow chart showing the recording device designation process. This process is executed when, for example, an item such as "recording device designation" is displayed on the menu screen and this item is selected. First, the connection status of the external recording device is confirmed using the IEEE1394 interface 5 (step S1). Next, the user is prompted to specify the genre assignment of the external recording device (step S
2). For example, as shown in FIG. 3A, the genre list is displayed at the top of the screen and the recognized external recording device list is displayed. The frame located to the right of this external recording device list is initially blank. The user operates a key of the remote control transmitter 15 to select a desired external device, brings the cursor to the genre list to change the color of the desired genre portion, and presses the enter key. Of course, the present invention is not limited to such a form, and the frame located on the right side of the external recording device list can be used as a pull-down menu for genre selection. By such an operation, the genre name is written in the frame located on the right side of the external recording device list, and the correspondence between the external recording device and the recording genre can be set. The MPU 17 stores the recording setting information in the memory 18 (step S3). After that, the user selects the program to be reserved, for example, on the EPG screen (step S4).

FIG. 4 is a flow chart showing the reserved recording execution process. This process is performed by the user for recording and recording registration of a program, and is started just before the broadcast start time of the program. Based on the information stored in the memory 18, the MPU 17 recognizes the genre of the reserved program and determines the external recording device from the recording setting information (step S5). Then, the determined connection with the external recording device is established using the IEEE 1394 interface 5. When the recording start time arrives (YES in step S7)
S), start recording. That is, the recording execution command is output to the external recording device specified using the IEEE 1394 interface 5, the reserved program reception process is executed, and the partial TS output from the TS decoder 3 a is specified via the IEEE 1394 interface 5. A control command is issued to the stream recording / reproducing unit 4 so as to supply it to the external recording device (step S8). During recording, the state of the external recording device is monitored (step S9), and when the recording end time comes (YES in step S10), the process ends. It should be noted that, in the state monitoring of the external recording device, when some trouble occurs, recording may be switched to the built-in hard disk 6.

As described above, in the broadcast receiving device with the recording device control function of this embodiment, for example, the external recording device 31 is assigned the genre of drama, and the external recording device 32 is assigned the genre of sports. By being in charge, if the program received by the recording reservation is a drama program, the external recording device 31 is automatically selected and recording is performed, and if the program received by the recording reservation is a sports program, it is automatically performed. Accordingly, the external recording device 32 is selected and recording is executed.

It should be noted that in the above embodiment, the genres are assigned to the external recording devices in advance, but for example, at the beginning, the user is allowed to select the external recording device at the time of recording reservation registration. Information such as which genre of program was recorded in the device is stored in the memory 18 as a history. For example, when there is information that the movie program was recorded in the external recording device 33 as the history, a process of recording the movie program in the external recording device 33 may be performed at the time of executing reserved recording thereafter. Good. Further, in this process, a confirmation message such as "Do you want to automatically record the movie program in the 3D-VHS after that? YES NO" may be output. Further, the history may not be all the past information, but may be the recording history of several times.

Further, the recording history of the genre of the program is stored in the memory 18, and when outputting the program guide based on the program information, for example, as shown in FIG. You may make it preferentially select and show a program.

Also, in the above description, allocation of external recording devices by genre has been described, but a process of recording a series program on a predetermined external recording device can be performed by the same method. For example,
Suppose the user has reserved a recording of a XX drama, MPU1
7 is the program information about OO drama series_
If it has an id, if it has a series_id, a message such as "This program is a series program. Do you want to perform series-specific recording?" is displayed, and the user can select whether to perform series-specific recording. Encourage. By operating the remote control transmitter 15, the user can notify the intention receiving device 30 that performs the video recording dedicated to the series. At the first stage of series-specific recording, for example, the user is asked which external recording device to use, and the external recording device to be used is determined. After this, the receiving device 30 determines that the reserved program series_i
An external recording device is automatically selected for recording based on d. A message prompting you to load a new recording tape in the external recording device may be displayed at the first stage of the series recording.

In recording a series program, it is desirable that the recording is continuously recorded on one recording tape in the order of episodes. Therefore, the MPU 17 acquires the tape position information (tape counter information, etc.) after recording the series program from the external recording device via the IEEE 1394 interface 5 and stores it in the memory 18. Then, when recording the next series program, the external recording device is inquired about the tape position information. If the tape positions do not match, a tape drive (rewind, fast forward, stop, etc.) command is issued to the IEEE 139 so that tape position information matching the stored tape position information can be obtained.
4 Interface 5 provides to external recording device. Then, the series program is recorded from this coincident tape position.

Further, the IEEE 1394 interface 5 may be used to execute simultaneous reproduction by a plurality of external recording devices and display a plurality of reproduced images by screen division processing. As a result, for example, while playing and watching a news program about football, it is possible to play and watch the football match. Further, in the above-mentioned example, the recording devices are sorted by the large genre, but the soccer programs may be sorted by the external recording device 31, the baseballs by the external recording device 32, and the like.
